To all whom it may concern: i with the concave pits in the ring 13 and13.

Be it known that I, ERNEST WILLIAM In the holes of ring -1- and 4: Iplace plugs v8, OOOKE, a citizen of the United States, residwhich haveconcave pits on the end nearest ing at Chicago, in the county of Cookand the rollers to accommodate the balls 9.

Said ring 1 1 is cut into two segt-ions.One of the rings is provided with a ments, and these segments are placedagainst take-up, which enables the rollers to conform ring 4 and 4, sothat the dividing point does 1 5 themselves to the varying diameters ofthe notcoine opposite the dividing point of ringi shafts or axles.and 1.

I place thering 13 and So I use a cylindrical ring, which is composed 13 inposition. I then lay balls 9 into the of two halves 13 and 13. Thesehalves are concave pits. The stay-bolts Gare then placed inortised atthe ends, so that one half will (it through the ring 13 and 1.3.

I then place the balls 9 for the thecircumference of the ring. On the inner opposite ends of the rollersinto the concave face of the two inner rings is a series of conpits ofthe rollers. I then place ringat and 4 cave pits, each pit carrying ametallic ball, together and put in the plugs 8. This ringet which act aspivots for the rollers 10 to reand 4E is then placed over the stay-bolts6 into 40 volve on. The rollers 10 are made of metal position and pins12 adjusted.

This cage is made so that 50 drilledthrough the ring 4 and i to correspond it can be removed easily from anaxle or shaft by simply taking off the ring 1 and 1 and taking out thetwo stay-bolts 6, which go through the interlocking segments on eachside of the ring. If the rollers become loose, I can take up the slackby simply taking off the rings 1 and land inserting thicker washers intothe cavities 7.

I am aware that cages for roller-bearings have been used, and I do not,therefore, claim roller-bearings in a broad sense; but

What I do claim, and desire to secure by Letters Patent, is-

1. In a cage for roller-bearings, the combination of rings made insegments interlocking one with the other, and balls supporting the endsof rollers, all substantially as and for the'purpose set forth anddescribed.

2. In a roller-bearing in which balls sup-' port the rollers, a cageformed of two main rings, one of which is provided with holes foradjusting plugs and Washers, a third ring bearing against saidlast-mentioned ring, and means for securing the cage together, allsubstantially as and for the purpose set forth
